• 04Student accountsA larger free tier for students and researchers — verify an academic email address, what it unlocks, and why it is re-confirmed every year.

The short version

Free solves models up to 500 degrees of freedom, keeps three cloud projects and one design check per project, and prints a watermarked summary report. Pro, at €19.99 a month or €13.99 a month billed yearly, removes those caps. A verified academic email address turns a free account into a student account with ten times every free quota. The full comparison is on Plans & limits; the pricing page is authoritative if the two ever disagree.

Principles

• No licence server. Nothing to install and no dongle.
• No per-material modules. Every design check that ships is in every paid plan, and every one added later will be too.
• No upgrade fees. New versions arrive in the tab.
• Cancelling deletes nothing. Your projects stay, and the .elproj file downloads on every plan — see Pausing or cancelling.
